PIN.

Application filed February 14, 1912.

To all whom it may concern:

Be it known that I, ERICK B. PETERSON, of the city and county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Pins;'

and I do hereby declare the following specification, taken in connection with the accompanying drawings, forming a part of the same, to be a full, clear, and exact de scription thereof.

The invention relates to pins of the character generally known as brooches, breastpins and the like, and more particularly to pins of this character in which the housing for the pin-tongue head and the catch mem her are formed integral with the back plate. In pins of this character as now constructed a multiplicity of operations are required to produce a finished pin, and it is the object of the present invention to reduce not only the number of operations, but also the amount of stock required, thereby greatly reducing the cost of manufacture of said ins.

To these ends the invention consists in the novel construction and combination of parts hereinafter described and more particularly set forth in the drawings.

In describing the invention in detail reference will be made to the accompanying drawings in which- Figure 1 is a plan view of a strip of blanks from which my improved pin is formed. Fig. 2 is a plan view of said blanks after the first operation of forming the housing for the pin-tongue and the catch member. Fig. 3 is a side elevation of Fig. 2 showing one of said blanks in longitudinal section. Fig. 4 is a similar view after the second operation of forming an opening in the side of the catch member. Fig. 5 is a plan view of the blank strip after the next operation of cutting out a completed back plate and at the same time forming an opening in the top of the pin-tongue housing in the adjacent blank. Fig. 6 is :a plan view of the completed back plate. Fig. 7 is a s de elevation of the same. Fig. 8 is an elevation of the pin-tongue. Fig. 9 is a side elevation of a completed pin broken away at each end.

Referring to the d awings, 1 represents a sheet of flat st ck which is cut out by suitable dies into the form shown in Fig. 1. As shown in said figure, there are a series of Specification of Letters Patent;

Patented'D' ec. 28, 1915'.

Serial No. 677,504.

longitudinally extending elongated openings 2 into one end of which extends a centrally located tongue or projection 3 and into the other end of which extends a centrally located tongue or projection 41-. Between the elongated openings 2 are two centrally located fan-shaped openings 5 and 6, the opening 5 being adjacent the fixed end of the tongue 3 and the opening 6 being adjacent the fixed end of the tongue 4. Extendmg into the flared end of the fanshaped opening 5 is a short tongue or projection 7 which is in line with the tongue 3. The edges of the stock 1 arepreferably scalloped at 8.

The blank sheet shown in Fig. 1 is operated upon by suitable dies or plungers to bump or bend up the sheet metal stnclnbetween the fixed end of the tongue 3 and the flared'end of the;fa n-shaped opening 5 to fornrthe hollow projection9 andat the same time to bump-up the sheet metal stock between the fixed end of the tongue 4 and the flared end of the fan shapedlopening 6 to form the hollow projection 10, as shown in Figs. 1 and 2. As also shown in said figures. said projections 9 and 10 are formed with flat parallel side-walls and the projection 9 is provided with flat parallel end walls 11 and 12, a portion of the outer end wall 11 being formed by the tongue 3 and a portion of the inner end wall 12 being formed by the tongue 7. The projection 10 is provided with a flat outer end portion 13, a portion of which is formed by the tongue 4, and the inner end of said pro ection 10 is left open, the inner edges of said projection being formed by the flared end of the fanshaped opening 6. The free end of the tongues 23 and 4 form rearwardly extending tail-pieces 14 and 15 for the attachment of the front plate 17.

The next operation consists in cutting out a portion of one of the sides of the projection 10 to form a horizontal opening 16, thereby producing a completed catch-member out of the projection 10, as shown in Fig. 4.

The next and final operation consists in forming an elongated opening 18 in the top of the projection 9, thereby producing a completed housing for the pin-tongue 19, and in cutting out the completed back-plate 20 from the sheet of stock. The pin-tongue 19 is mounted in the completed housing by passing the pointed end through the open bottom of said housing and through the elongated opening 18 in the top thereof and is held in said housing by the front plate 17, as shown in Fig, 9.

With the above construction it will be seen that by forming the openings 2, 5, and 6 in the sheet stock 1 a less amount of stock is employed-and said sheet stock is weakened around the point where the projections 9 and 10 are bumped up so that said projections can be formed by one bumping operation, and it will be seen that the tongues 53, 4:, and being bent to form the closed end portions of the projections 9 and 10 thereby produce a seamed housing and catch-member. It will further be seen that the tail-pieces 1-1 and 15 can be made any desired size or shape and that the openings 5 and 6 facilitate the drying of the coloring or plating solutions which enter between the front and back plates.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a device of the character described, the combination with a front-plate, of a back-plate formed from tlat sheet stock havingaa longitudinally extending opening adjacent each end, an integral pin-housing formed by forcing up the metal adjacent the end of one of said openings, an integral catch-member formed by forcing up the metal adjacent the end of the other of said openings, said catch-member being open on the end adjacent the end of said last mentioned opening, and a pin mounted in said pin-housinx 2. A back-plate for pins formed from fiat sheet stock having a series of openings and a series of tongues extending into said openings and having an integral hollow projection between and adjacent said openings provided with flattened sides, said tongues being bent to form end portions for said hollow projection.

3. A back plate for pins formed from a flat metal blank having a longitudinally extending fan-shaped opening adjacent each end, an integral pin-housing formed by forcing up the metal adjacent the flared end of one of said fan-shaped openings, and an integral catch member formed by forcing up the metal adjacent the flared end of the other fan-shaped opening, said catch-member being open on the end adjacent the flared end of said last mentioned fan-shaped opening.

hA back plate for pins formed from a flat metal blank having a longitudinally extending fan-shaped opening adjacent each end, a. tongue extending into the flared end of one of said openings,tand a centrally located outwardly extending tongue at each end of said blank, the metal between said fan-shaped openings and said outwardly extending tongues being bumped up to form hollow projections with flattened sides and said tongues being bent to form end portions for said hollow projections.
